Stats: 18 y/o, 6ft tall, 76kg (~170lbs)

Just came off 12 weeks of 5/3/1 and have made some impressive strength gains now switching to 6x a week PPL.

My goal really is to bulk to look as big as I can, cut to low bf% and then maintain while I focus seriously on competing in MMA.

It’s gonna take time to bulk and cut to low bf%, so what would be the best way to get this down while also training MMA at least twice a week? MMA training burns a lot of calories making it harder to bulk, but obviously fighters have a way of doing it. Anyone got advice?
